A Framework To Predict High Risk Roadways For Pedestrians In Tennessee, Zane Hunter Pannell

Masters Theses

Pedestrians and bicyclists are a class of vulnerable road users that are often over-represented in incapacitating injury or fatal crash statistics. Because non-motorized trips are vital to many urban and rural residents for utility or recreation and exercise, it is essential to identify safety deficiencies in our existing transportation infrastructure to address rising injuries and fatalities among this group of road users. As the economy continues to struggle and fuel prices remain high, many cities and rural transportation agencies are seeing large increases in bicycling, walking, and transit ridership. While passenger car fatalities have shown sharp declines in the last …

Driver Fatigue Enforcement Techniques And Their Effect On Crashes, Carrie Mohlman

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Fatigued driving is a type of driver impairment caused by a lack of sleep, sleep disorders, long drive times, etc. Fatigued driving enforcement aims to improve safety by removing impaired drivers from the roadway. While fatigued driving is detrimental to safety, there exists the issue of identifying fatigue. There is a range between being awake and asleep and, in order to improve safety, enforcement officers must be able to identify the point at which drivers are impaired.

This thesis investigates potentially effective fatigued driving enforcement techniques for use by enforcement officers. These techniques were investigated through three primary means: a …

Spatial Factors Impacting Non-Motorized Exposures And Crash Risks, Farhad Abasahl

Masters Theses

This research investigates spatial factors, that impact non-motorized exposures and crashes, and examines the relationship between exposure at signalized intersections and crash frequencies involving pedestrians and bicycles at a census tract level. The four Michigan cities of Ann Arbor, East Lansing, Flint and Grand Rapids are examined. After completing an extensive literature review to provide a list of required data, 92 intersections are selected from the four cities to collect pedestrian and bicyclist counts. Five-year crash records, special attractions, non-motorized facilities and transportation infrastructure data for the four cities are gathered for the four cities. This data are later mapped …

Urban Parking Economics And Land Consumption: A Case Study Of New Haven, Connecticut And Cambridge, Massachusetts, Bryan P. Blanc

Honors Scholar Theses

It has become increasingly apparent that providing copious off-street parking has deleterious effects on urban form and function. This study compares parking policy in New Haven, Connecticut and Cambridge, Massachusetts that have pursued very different types of parking policies that have resulted in different outcomes in terms of land use. Since 1951, off-street parking provision has increased by nearly 400% in New Haven, meanwhile both employment and residential population have declined in the city. In contrast, off-street parking provision in Cambridge has risen around 140% since 1952, while employment and residential populations in the city have increased by 50% and …

Partners On Campus: Open Access Transportation Research At Purdue University, David Scherer

Libraries Faculty and Staff Presentations

In the third community webinar presentation on regional and community partnerships, David Scherer, the Scholarly Repository Specialist at Purdue University, described how institutional repositories can support community engagement through the rewards of the partnership between Purdue's institutional repository, Purdue e-Pubs, and Indiana's Joint Transportation Research Program (JTRP). The Purdue Libraries and the Purdue University Press have worked to archive and showcase the fruits of over 75 years of strong collaboration between Purdue University and the Indiana Department of Transportation on research that has a significant impact on the safe and efficient operation of transportation systems throughout Indiana, the United States, …

Estimation Of Performance Indices For The Planning Of Sustainable Transportation Systems, Alexander Paz, Pankaj Maheshwari, Pushkin Kachroo, Sajjad Ahmad

Civil and Environmental Engineering and Construction Faculty Research

In the context of sustainable transportation systems, previous studies have either focused only on the transportation system or have not used a methodology that enables the treatment of incomplete, vague, and qualitative information associated with the available data. This study proposes a system of systems (SOS) and a fuzzy logic modeling approach. The SOS includes the Transportation, Activity, and Environment systems. The fuzzy logic modeling approach enables the treatment of the vagueness associated with some of the relevant data. Performance Indices (PIs) are computed for each system using a number of performance measures. The PIs illustrate the aggregated performance of …
